Abstract

To study the clinical features of strabismus in premature baby, we reviewed the hopital records of out-patients who visited Seoul National University Children's Hospital from March 1995 to December 1995 with strabismus and prematurity. We analysed the type and onset of strabismus, history of acute retinopathy of prematurity, surgical treatment for retinopathy of prematurity, retinal sequelae of retinopathy of prematurity and abnormality of central nervous system. Sixty-five patients were included in this study. Thirty-eight were male and 27 were female. Age of first visit was 18.0+/-33.7 months(mean+SD). Gestational period was 32.3+/-2.9 weeks. Birth weight was 1742.0+/-486.5g. Follow-up period was 53.1+/-37.3 months. Onset of strabismus was 15.6+/-20.5 months ater birth. Forty-two(64.6%) were esodeviation and 20(30.8%) were exodeviation. One was superior oblique palsy. And two were inferior oblique overaction. There was no statistically significant relationship between the type of strabismus and the history of ROP, surgical treatment for ROP, retinal sequelae of ROP, abnormality of central nervous system respectively(Chi-square test, P>0.05). This study analyses the clinical features of strabismus in premature baby and can afford some information for strabismus in premature baby.
